Threat Intelligence Briefing

Threat activity has surged, with global threat reports up 30.9% compared to the previous six-hour window. The dominant threat vector remains SSH brute-force attacks. While there's no specific targeting of Nordic countries in this period, Russia (RU) and Romania (RO) are the leading origin countries for attacks. The top attacking IPs, originating from RU and RO, are engaged in concentrated SSH brute-forcing. No significant Tor exit node activity or specific ISP abuse was observed. Given the spike in SSH brute-force attempts, monitor networks originating from ASNs associated with observed Romanian and Russian IPs. Focus on hardening SSH configurations and implementing multi-factor authentication. Track emerging brute-forcing patterns targeting other services beyond SSH, and correlate with potential credential stuffing campaigns.
